Analyze the graph and identify some factors that may contribute to the rotifer population leveling off in the absence of water fleas. Explain your answer in 1–2 sentences.

Answer 1

The rotifer population levels off in the absence of water fleas due to limited resources and competition for food.

Step-by-step explanation:

The factors that may contribute to the rotifer population leveling off in the absence of water fleas are limited resources and competition. Without water fleas as a food source, the rotifers may struggle to find enough food to sustain their population, leading to a leveling off of population growth.

Answer 2

(Leveling off = it stays the same even though it had a increasing period) When looking at the end of the graph you can see that it came back to what it was, which means the rotifers are not increasing anymore. That's because of the carrying capacity (a species' average population size in a particular habitat), and the carrying capacity in this situation is the flask. Therefore the flask has limited space.
